The "hold" queue contains *messages*, transports deliver (groups of) recipients. You can get new *messages* to be held, but mail already in the (active or deferred) queues does not go through cleanup again. If you specify a non-existent transport, in the transport table, and don't get too annoyed by the warnings, you can get the *effect* of "defer_transports", without reloading, for mail that is not yet active. If you are willing to reload later (when you want to re-enable the transport) a drastic step is to delete the transport socket in /var/spool/postfix/private/, the transport won't work until you reload, and you can't bring it back any other way if you do that. -- Viktor.
